<Steps>

## Install next-themes

Start by installing `next-themes`:

```bash
npm install next-themes
```

## Create a theme provider

```tsx title="components/theme-provider.tsx" showLineNumbers
"use client"

import * as React from "react"
import { ThemeProvider as NextThemesProvider } from "next-themes"

export function ThemeProvider({
  children,
  ...props
}: React.ComponentProps<typeof NextThemesProvider>) {
  return <NextThemesProvider {...props}>{children}</NextThemesProvider>
}
```

## Wrap your root layout

Add the `ThemeProvider` to your root layout and add the `suppressHydrationWarning` prop to the `html` tag.

```tsx {1,6,9-14,16} title="app/layout.tsx" showLineNumbers
import { ThemeProvider } from "@/components/theme-provider"

export default function RootLayout({ children }: RootLayoutProps) {
  return (
    <>
      <html lang="en" suppressHydrationWarning>
        <head />
        <body>
          <ThemeProvider
            attribute="class"
            defaultTheme="system"
            enableSystem
            disableTransitionOnChange
          >
            {children}
          </ThemeProvider>
        </body>
      </html>
    </>
  )
}
```

## Add a mode toggle

Place a mode toggle on your site to toggle between light and dark mode.

<ComponentPreview
  styleName="new-york-v4"
  name="mode-toggle"
  className="[&_.preview]:items-start"
/>

</Steps>
